HaftGrund EG

Remineralising, adhesion-promoting primer for the following coatings inside and outside

    • LV Texte

    Field of Application

    White pigmented, special priming paint (wash primer) for covering priming coats on interior and exterior surfaces before applying finishing coats of dispersion, dispersion-silicate and silicone resin paints.
    Adhesion-promoting primer on on smooth, sound/stable substrates, e.g. gypsum plasterboards, concrete, as well as slightly absorbent mineral renders CSI - CSIII according to DIN EN 998-1, gypsum and ready-mixed renders PIV according to DIN EN 13279-1 and gypsum building boards. Especially on gypsum boards, a risk of spalling of thin gypsum putty layers is significantly reduced. As a priming coat with good grip before wallpapering of all kinds on smooth, slightly absorbent substrates.

    Material Properties

    • Silicifiable for following coats with dispersion silicate paints
    • Emission-minimised, solvent-free, unplasticized
    • Grip priming coat especially on thin gypsum filler
    • Extends the open time for subsequent coats
    • Free of preservative
    • Suitable for allergy sufferers "Deutsche Haut- und Allergikerhilfe E.V." (German Skin and Allergy Aid Association)
    • Adhesion-promoting on slightly absorbent substrates

    Material Base / Vehicle

    Modified, remineralising plastic dispersion according to DIN 55945.

    Suitable Substrates

    The substrates must be sound/stable, dry, clean, and free from all substances that may
    prevent good adhesion.In Germany: Follow VOB, Part C, DIN 18 363, section 3. For substrate pre-treatment, please also observe our Technical Information No. 650 "Substrates and their pre-treatment".

    Substrate Preparation

    For interiour use: Note Q2/Q3 Filling / thin gypsum layers < 0.5mm. When using gypsum-containing, hydraulically setting filling compounds in quality level Q2/Q3, a transparent, water-based primer is recommended. For this, in Germany we refer to the Maler&Lackierer leaflet No. 2 -9/2020 "Adhesion problems of coatings on filled gypsum (cardboard) boards" of the Bundesverband Farbe, Gestaltung, Bautenschutz and the Bundesausschuss Farbe und Sachwertschutz. As an alternative to gypsum-based Q3 filling, filling with pasty filling compounds has proven successful.

    Method of Application

    HaftGrund EG can be rolled, brushed and sprayed.

    Thinning

    Undiluted, or with max. 3 % water or CapaSol Concentrate adjustable to working consistency.

    Surface Coating System

    As a covering primer coat before following coat with dispersion and dispersion-silicate paints.

    Consumption

    Depending on absorbency and condition of substrate, approx. 150-200 ml/m2.
    Determine exact consumption and degree of dilution by trial coating on site.

    Application Conditions

    Lower temperature limit during processing and drying:
    Material, circulating air and substrate temperature: min. + 5° C to max. + 30°C.

    Drying/Drying Time

    At +20 °C and 65 % relative humidity recoatable after approx. 12 hours. Lower temperatures and higher humidity extend the drying time.

    Tools

    Rolling application: rollers with a pile height of 13-18 mm

    Tool Cleaning

    Wash out tools and implements with water after use.

    Airless Application

    Spray angle: 50°
    Nozzle: 0.021-0.025
    Spray pressure: 150 - 180 bar

    Note

    Compatibility:
    To obtain the special properties, mix HaftGrund EG only with CapaSol Konzentrat, CaparolColor Vollton- und Abtönfarben or AmphiColor Vollton- und Abtönfarben. Do not add any other products.

    Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)
